Description
Technical field
The utility model relates to hygiene article sector more particularly to a kind of concave-convex absorptive cores.
Background technique
The absorptive core for the amenities being currently known can substantially be divided to two kinds.One is compound core bodies, generally by outermost two
Layer dust-free paper, middle layer non-woven fabrics and two layers of SAP (hydroscopic high-molecular resin) composition；Another kind is cotton core body, by dust-free paper or
Hydrophilic cloth package Time of Fluff Slurry and SAP are formed.Other than above-mentioned common structure, also there is part of the manufacturer to do on absorbent structure subtle
Adjustment, add one layer of wood pulp again such as in structure, and on cotton core body use emery wheel pattern pressing type.
Above-mentioned core be after absorption of liquid it is planar, it is big with skin contact area, and the SAP amount that can be added has
Limit, add a large amount of SAP be easy to cause SAP slide and with obvious granular sensation, after imbibition will occur core layering with sliding heap
Product needs the usage amount by increasing hot melt adhesive when adding a large amount of SAP, otherwise a large amount of SAP is easy movement, causes to be unevenly distributed
It is even, and hot melt adhesive will excessively cause infiltration rate to be decreased obviously with gas permeability, and feel is stiff, environment-friendly type is poor.
Utility model content
Therefore, for the above content, the utility model provides a kind of concave-convex absorptive core, and it is high to solve existing absorptive core
Olistostrome easily occurs before molecular material layer imbibition, uses the big defect of hot melt glue amount.
In order to achieve the above objectives, the utility model is achieved through the following technical solutions:
A kind of bumps absorptive core, including base fabric, top layer hydrophilic nonwoven fabrics and SAP particle between the two, the top
Layer hydrophilic nonwoven fabrics have the hollow protrusion of equally distributed array, with Weak link point between the hollow protrusion and base fabric
Mode connects to form cavity, the SAP particle be it is a plurality of, and be not connected between each other, the SAP particle with it is described hollow convex
It rises and is located in its cavity correspondingly, the bonding force of the Weak link point is less than the SAP particle and absorbs the expansion after liquid
Power, it is each it is hollow protrusion between neutral gear formed diversion trench.
A further improvement is that: a plurality of strong bonding points are additionally provided between the base fabric, top layer hydrophilic nonwoven fabrics, it is described
Two hollow protrusions are included at least between strong bonding point, the bonding force of the strong bonding point is greater than the SAP particle and absorbs liquid
Expansive force afterwards.
A further improvement is that: the hollow raised base diameter is 2-5 millimeters, and the Weak link point quantity is uniform minute
4 to 6 points of the cloth in raised brim.
A further improvement is that: the hollow protrusion is longitudinally formed plural parallel lines, and around each hollow protrusion
All uniform ring is around 5 hollow protrusions of distribution.
A further improvement is that: the other side of the base fabric be also equipped with the mutually isostructural top layer hydrophilic nonwoven fabrics and
SAP particle.
By using preceding solution, the beneficial effects of the utility model are:
1, the utility model structure is simple, and production method is simple, and cost can be effectively reduced, improve production efficiency；Pass through
Hollow protrusion is set on top layer hydrophilic nonwoven fabrics, plays the role of storing SAP material, it, can be in conjunction with surrounding tie point
Fixed function is played to the SAP before imbibition expansion, prevents its olistostrome, and the bonding force by the way that the Weak link point is arranged is small
Expansive force after the SAP absorbs liquid, expansion struts tie point after SAP can be made to absorb liquid, expands absorptive core
Uniformly, connection is in addition put between top layer hydrophilic nonwoven fabrics and base fabric, the hot melt adhesive used is fewer, the feel of entire absorptive core
Preferably, also more environmentally friendly health.
2, the strong bonding point of setting is further improved because there is sufficiently strong cohesive force, will not be strutted by SAP, imbibition is expanded
SAP afterwards plays position-limiting action, and SAP is layered after preventing expansion and olistostrome.
3, the hollow raised base diameter for being further improved setting is 2-5 millimeters, each hollow protrusion and base fabric
Point be connected as being evenly distributed on 4 to 6 points of raised brim, belong to the raised size and connection points of optimization, diameter is too small
The amount for then storing SAP is too small, and absorbency does not reach requirement, and the too big then water imbibition of diameter is beyond equal after needs and absorptive core expansion
Evenness is not easy to control, and edge setting 4 or 5 and tie point, is enough to play fixed SAP material effects, too many cost of idleness, very little
Optimum state is not achieved in fixed effect.
4, the hollow protrusion for being further improved setting is longitudinally formed plural parallel lines, and each hollow protrusion week
Enclose all that uniform ring is around 5 hollow protrusions of distribution, groove can form unobstructed diversion trench between the array of protrusions of formation, be conducive to
Air flowing before imbibition expands when skin contact, the flowing of liquid makes uniform absorption when being also beneficial to absorb liquid, reduces skin
Contact of the skin with liquid.
5, the other side for being further improved the base fabric of setting is also equipped with the mutually isostructural top layer hydrophilic nonwoven
Cloth and SAP particle, can make absorptive core absorbent properties more powerful, two-sided can use.
